Ok so last time i put my mothers PC in RAID1 the whole thing turned out in a god awefull mess.... So her PC was getting alot of BSOD's and after some testing and resetting the BIOS i found out it was the RAM. So when i tried to put the drives back into RAID something went wrong and basically everything got lost the OS was corrupted and got wiped..... luckily i managed to recover about 80k photo's with some recovery software.

Anyways now i want to put the 2 drives back in raid again... bought an extra SSD for OS and Programs so the HDD's will only be used for documents and stuff and an external HDD for backups.

So should i use the Motherboards RAID controller or try to put the drives in RAID trough Windows?

And yes i know they both suck but i'm not going to buy a RAID Controller.

Hardware raid is always better than software raid, it allows the motherboards raid controller to do the work instead of eating up CPU cycles with software.

I guess hardware raid it is then.
But what if i need to rebuild the RAID again? Last time it went pretty bad and corrupted Windows and wiped 90% of the drive in the process. Was it just a case of bad luck or is rebuilding the array trough onboard raid controllers just not reliable?
